Filed: 1947-06-23
Abstract: <PICT:0627150/III/1> <PICT:0627150/III/2> An apparatus for decorating chinaware comprises a freely rotatable chinaware receiving chuck and a driven pigment-carrying applicator roller adapted to ride upon the face of and rotate a piece of chinaware resting on the chuck, and means for supporting the roller and allowing it to undulate in following the configurations in the face of a piece of chinaware. Referring to the drawings, a number of pieces of dinnerware 55 are placed upon the <PICT:0627150/III/3> <PICT:0627150/III/4> chucks 10 and each pair of arms 14 are swung horizontally about their studs 56 so that the applicator rollers 35 rest on the plate edges.  The thickness of pigment film supplied to rollers 35 is controlled by adjusting screws 43 which control the clearances between the bottom of the pigment wells 39 and the drum faces 29. When the motor 6 is started, table 2 rotates about stationary shaft 3 and the pinions 47 on the ends of the flexible shafts 48 also individually rotate in passing around stationary gear-wheel 45.  The rotation of the pinions 47 and consequential rotation of flexible shafts 48 and bevelled gears 32 and 31 cause rotating drums 29 to rotate applicator rollers 35.  As the applicator rollers rest upon the dinner plates which in turn rest upon the freely rotatable chucks, the applicator rollers cause the plates and chucks to revolve and so apply pigment to them. While the table 2 is rotating and applicator rollers 35 are both revolving the plates and applying pigment thereto, the rearward extension portions 54 of cross-piece 53 are riding on the face of stationary cam 49.  As the rearwardly-extending portions 54 ride up upon the raised portion 50 of the cam face, the push rods 52 are moved outwardly against the feet 16 thus swinging their pair of arms 14 upwardly into the position shown by dotted lines in Fig. 2.  Here an operator manually removes the decorated plate and inserts a new one.
